I have the Dell Inpsiron 15 7000 gaming laptop. I like to play an online web game that requires pressing the arrow keys to maneuver. I either tap the keys or hold them down to move. Often when I hold them down one of the arrow keys decides to not work at all. It happens randomly and it really screws me up. It does not happen when I use a USB keyboard but I would much rather use the built in keyboard. I tried messing with the Keyboard setting and I do not believe that they are apart of the issue. I was hoping someone could help me out here. I am not too tech savy and could not find anything at all to fix it.
